@ RTTY KEY jack (T)
Jack for FSK operation. Connect this directly to the low
voltage (5 V DC or less) terminal unit output using an RCA
plug. DO NOT connect a 60 MA local-loop direct: use a
keying relay to provide a switched ground.
Power connector
Connector for AC power source. Make certain the
transceiver's voltage selector is adjusted to your local line
voltage BEFORE turn-on.
@) AC FUSE
This fuse protects the power supply against short circuits.
Never use a higher amperage fuse than specified; it will
eventually cause extensive damage. If the fuse blows, try
to determine the cause before replacing. For 120. volt
operation, use a 6 ampere fuse. For 220/240 volt, use a 4
ampere fuse.

imately 10 V DC.
